• After the previous report (ref. 1), two types of survey on the contamination of food by fall-out in Japan were carried out. The one is the standard diet survey, in which food materials were purchased at 4 localities according to the same standard recipe 4 times a year and radioassayed for ^<90>Sr and ^<137>Cs. Since the autumn of 1961, the food materials collected were divided into 7 groups (cereals; pulses, nuts and fruits: leafy vegetables; root vegetables; sea weeds; fish and shellfish; and milk, meat, eggs and poultry;) to know about the size of role of these food groups in human body contamination. The other is the daily diet survey, in which one day amount of diet of 10-20 families selected at random in each of 7-10 localities in Japan twice a year. The results obtained by the two methods were compared with each other. Both showed similar tendency as general. However the values were always higher in daily diet survey than standard diet survey (Fig. 1). The results of both surveys show generally that vegetables are major source of both ^<90>Sr and ^<137>Cs in Japan in most cases and the milk is entirely minor source of contamination (Table 1). The both survey results were always higher in Japan sea side than in Pacific side in contaminated level (Figs. 2-6). And it seems to be no difference between urban and rural. The relationships between the contamination level of diet and that of fall-out rate and deposited were estimated, using the values of standard diet in Tokyo.
